Migros, the biggest supermarket chain in Switzerland, is now exclusively sourcing salmon certified by the Aquaculture Stewardship Council (ASC) for its fresh fish counters, making the full range of their salmon products ASC-certified.

The switch happened on July 8, and includes not just branded products, but the retail giant’s own brand, M-Budget, as well, which carries smoked salmon.

The retailer is always looking to switch to certified products wherever possible, and salmon remains their most popular species, Migros Chief of Ecology Sandra Hinni told IntraFish.
